The Northern Fur Seal is a marine mammal found primarily in the North Pacific Ocean. They are known for their thick fur, which is a mix of dark brown and gray, and their external ear flaps. These seals are social animals, often seen in large colonies on rocky shores and beaches, especially during the breeding season. Northern Fur Seals primarily feed on fish and squid, using their sensitive whiskers to detect prey in the water. They are known for their agility in the water, diving to depths of over 200 meters. Conservation efforts are in place to protect their populations, which have faced threats from hunting and environmental changes.
